Q: What is wrong with the application of human excreta as seed bed fertilizer one day before sowing and nursery?
Answer: Human excreta is a good fertilizer, but it should be fully decomposed before it can be applied. Generally, it should be applied to the seedbed one month in advance and then ploughed and covered so that the fertilizer and bed soil can be fully mixed and evenly attached. Above the bed soil. The use of uncommatured human waste or other unfamiliar livestock organic fertilizers or home-grown fertilizers, in addition to heat-damaged cotton seed produced during the fermentation process, can also result in reverse osmosis-damaged cotton seed in excess concentrations. Therefore, despite the application of organic fertilizer as seedbed base fertilizer, one must be fully decomposed; the other must be applied 20-30 days in advance; third, to control a certain number, the general use of per os of seedbed maturity of 1000 kilograms of human waste is enough.
Q: If inorganic fertilizers are used, what kind of fertilizer should be used as seed bed fertilizer?
Answer: The available varieties include multiple compound fertilizers or nitrogen-phosphorus compound fertilizers. In the ternary compound fertilizers, high-content compound fertilizers may be used, and low-content compound fertilizers may also be used, but urea may not be used as the base fertilizer. The multiple nutrient fertilizer has a complete nutrient content, and the release process is slower than the single nitrogen fertilizer, and can gradually meet the needs of the growth of the cotton seedlings, and can play a role in cultivating the cotton seedlings. The urea has an inhibitory effect on the germination of the cotton seed. The biuret released during the decomposition process can make the cotton seed dehydration germ poison and rot. Therefore, do not use urea as the base fertilizer for the cotton seedbed.
Q: How about the application amount of inorganic fertilizer for bedbed fertilizer?
A: Inorganic fertilizers are used as seedbed fertilizers. Generally, 0.75-1.0 kg of compound fertilizer with nitrogen, phosphorus, and potassium content of 45% per 10 m2 of seedbed is applied. If compound fertilizers with nitrogen, phosphorus, and potassium contents of 25% are applied, corresponding Increase the amount of application, while applying side soil mixing. Over-application can also cause reverse osmosis to inhibit the growth of cotton seedlings.
Q: What other fertilizers can be used as base fertilizer for cotton seedlings?
A: There are a lot of companies that produce organic fertilizers that are producing all kinds of seedbed fertilizers. One is bio-organic fertilizer. Each 10m2 seedbed can be applied with 10-12.5kg. One is bio-organic compound fertilizer, which contains inorganic fertilizer and can administer about 7.5kg per 10m2.
